パーティクルシステムがどのようにトランスフォームのスケールを適用するかを管理します。
| Hierarchy | Scale the Particle System using the entire transform hierarchy. |
| Local | Scale the Particle System using only its own transform scale. (Ignores parent scale). |
| Shape | Only apply transform scale to the shape component, which controls where particles are spawned, but does not affect their size or movement. |
